Reinstall the wheel speed sensor, and check
the mounting position (see page 19- 173).1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle. Drive the vehicle at 20 km/h
(13 mph) or more, and go a distance of 100 m
(328 ft) or more.
NOTE: Drive the vehicle on the road, not on a lift.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the wheel
